i've bought an iphone x with 85 percent battery health but after 1 day it drops to 83 percent......................??

さんによる

I have same problem i have xs max. Yesterday my battery was at 95% but today it is on 93%

さんによる

It doesn’t really matter your battery health will never drop below 80 percent unless ur charge cycle has surpassed 500 cycles so relax and enjoy your phone and when the time is due you change the battery nothing else!

Yesterday I checked out my iPhone X battery was 86 and next morning I woke up and put my phone on charger and when I checked my phones battery health it was 82. Do my phone’s battery need to replace?

That’s not normal. See if Apple will get you a replacement.

I agree that this is quite a rapid drop in capacity but Apple will only warranty a battery if it gets to 80% within the first year.

@refectio Ah, I wasn't aware of that. I suppose you could just wait for it to drop more and then get a warranty.

"Health" is a measure of discharge rate. The phone has logic that calculates the remaining capacity and compares it to the battery spec. There are apps, sometimes built-in, that will discharge a battery when nothing else is happening for a short time, calculate the discharge rate from the voltage drop, and interpret that as "health".

Every time you discharge a Li-Ion battery to below 10% of spec capacity or charge it to above 95% spec capacity it is damaged slightly, loses capacity slightly faster than normal. The charger furnished with a phone works with the phone to prevent over (+95%) charging, an aftermarket charger may not.

Degradation may seem to be excessive during the early part of a battery's life. Li-Ion batteries have a learning curve and increase capacity during the first series of charging cycles. That's why EVERY device that uses them says to FULLY charge them BEFORE first use. Few users do this.

(I tested a Li-Ion battery pack with a new drill after an initial timed, not indicated, full charge, and timed how long the drill would work, bu drilling holes in wood. I repeated this 5 times. Each time the run time increased. The "capacity" after 5 charges was 20% more than the first time.

For you, more important than absolute "health" is whether its "health" continues to degrade faster than 0.75% per month. A typical Li-Ion phone battery will provide 70% capacity after 3 years of being in continuous service.

I bought an iPhone 7 on a reseller and the model letter starts with “M” and the battery life indicates 91 % but after 3 months of usage it drops to 89 %. Does the rate of degradation is normal?

3% is excellent for what is probably an original battery. Live with it until it gets to 70%.
